New loop high temps 65C

[fenchu]

Hi , i was hoping i could get some advice with referance to my setup i recently moved to water cool and built a loop for my titan-x the loop consists of

EK - XRES 140 D5 vario
Black ice GT Stealth 240 mm Radiator
2x Aerocool DS Edition fans Pull
2x Shark fin push
EK Water Blocks EK-FC Titan X - Acetal+Nickel & backplate

The only component on this loop is my Titan X the radiator is at the bottom of my case and my case is a phatnek enthoo prime see picture :-

Spoiler

I was recommended the components via another thread , my temps after 15 minutes of heaven stabilise at 65c which seems way to hot. The radiator is hot to touch and im not sure if its enough for my setup.

Should i install another 420 or 480 radiator into my loop with exisiting radiator or get rid of the raditor im currently using and rebuild loop with 420 or 480 radiator in top of my case ?

XSPC EX480 120mm Radiator - Black

XSPC EX420 Triple Fan Radiator

these are the radiators i was looking at , at present i dont feel comfortable using my pc as i say under load im hitting 65c which cant be good for the tubing with it being rated at 60c same with the pump.

**edit raised case of floor half a meter removed air filter put it next to open window and still roughly same results 15 minutes of heaven and 63c.


*** solved / Fixed

Maybe try the rad in either push or pull, to eliminate any kind of problem with the mismatch of fans causing an airflow problem.

Also, what exhaust fans have you got in the case? Any in the top? The hot air might not be getting pulled away quick enough.

tryed rad in both push and push pull exhaust fans 2x 140mm top of case and 1 in back 2 are intake in front all are Phanteks PH-F140SP. Except the ones on radiator

Can you try raising the case off the floor and see if that makes any difference? It sounds like it's restricted air flow more than anything if your radiator is feeling hot to the touch.

Done this and ammended first post , rasied case half a meter of ground removed dust cover and only a 2c difference within 15 minutes of heaven i was at 63c.

 

[fenchu]

65c aint really that bad when some GPU's run in the high 80s on air?

As far as im aware the pump has a temp limit of 60c and the tubes 60c so i would consider it to be bad.

wel ive just ordered some more parts :-

XSPC EX420 Triple Fan Radiator
Phanteks PH-F140SP 140mm Fan - Black / White
XSPC HighFlex Hose 3/8" ID, 5/8" OD, 16/10mm, 2m, Clear
EK Water Blocks EK-ACF Fitting 10/16mm - Black

as i already have 2 phanteks in top of case i only needed to order 1 for the 420 radiator.

 

[fenchu]

as said before its all about the heat has no where to go. either put your rad in the front or top or do as i have done and stand the feet on some chocks of wood

well i tryed putting the case on feet approx half a meter high but only saw a temp difference on 2c. To put the res in the front thou i need to remove the drive bays do i not on the primo ? cant move it to top as i just ordered a 420 rad .

That's the core temp not the actual water temp... That will be much below 63°C...
Still not very good though. I have just finished a new WC build in and enthoo primo with 2x 480mm rads and my temps aren't great... Still working through it all methodically to find what's up.

I need to get sensor for water temp to get better idea of whats happening there.

edit just seen he has raised the case. are you sure you have all the air out of the gpu block

Well i have no air bubbles in line or resorvoir so im guessing yes + the block seems to be working right ie heat transfered to radiator.

+ is the GPU block correctly seated. What thermal paste did you apply? did you apply the right amount?

thin even layer spread using mx4.

Just want to say thanks for the help so far guys im sure we can get to bottom of this

 

[fenchu]

just because you dont have any in your line or resevoir doesnt mean that there isnt any in the block water conducts heat so it will appear that its working. sorry but speaking from experience it is one of two things: 1 the block isnt seated properly :2 air in the block

Well im new to this so appreciate the feedback from more experienced users like yourself. Im 9/10s sure the block is seated correctly but i can redo again just for piece of mind when i fit new rad.

To get air out of the block then is there any effective way , as far as aware im best to tilt case side to side flicking power on / of.

Was thinking about upgrading fans as well on 240 to these :-

https://www.overclockers.co.uk/showproduct.php?prodid=FG-016-CS&groupid=701&catid=2331&subcat=4

Corsair Fan, SP120 PWM High Pressure Fan 4 pin

or these :-

not just sideways i had to do most of mine upside down and every direction possible. also shake it like mad.

Ok ill give that a go once kids gone to bed and report back thanks

 

[fenchu]

What speed is the pump running at ?

im on setting 5 at moment did try 2 but temps were about same 3c differnce roughly.

Flipped case over numerous times and shaken side to side but still no good running heaven same temps will try again later.

quick question , should the fins on the radiator be warm at all .. as there the only things cool.

 

[fenchu]

yes they should be warm and sorry to sound like iam repeating myself but it sounds like you have air trapped. mine took 2 solid days of rotating and shaking and turning the pump on to bleed mine.

there not warm at all even if i stop fans , the front entry ports and rear + sides are hot would this point to air trapped in radiator as the fins are not even slightly warm ?

 

[fenchu]

yeh flushed the radiator through around 7 times.

I had the mrs fill radiator whilst i was flicking power on psu she was a bit slow and the res emptyed briefly as she was filling ... im guessing this has put a bubble in rad obstructing flow given the fins are not warming up at all ?

I thought that given i could not see bubbles in res or lines i was clear but perhaps not.

If i cant remove via shaking etc , i guess im going to have to empty loop and redo .. which i can do when the 420 rad arrives tuesday.

****edit Just tryed 10 mins with heaven and fans turned of on radiator and the fins within radiator arent even warming up however around the edge of the rade sides front and back (housing are all hot)

 

[fenchu]

It might be an idea to leave the side of the case off and try and turn the rad so the fans can pull air in without any restriction. Rather then corsair sp120. (Which I use), you could consider ek Vardar f1/f2 or Gental typhoon which allow you to run the fans at full rpm with low noise.

ill look into those shortly thanks

Have you tried running it with the top blanking plate off your res?

yeh no difference

 

[fenchu]

. Rather then corsair sp120. (Which I use), you could consider ek Vardar f1/f2 or Gental typhoon which allow you to run the fans at full rpm with low noise.

was just looking at the ek vardar but the static pressure is half that of the sp120s , althougth i did check a video on the sp120s and they are noisy. Im guessing i can control this thougth my fan controller when not stressing gpu ?

 

[fenchu]

The Vardars out perform the corsair sp

The reservoir is very full so it might be an airlock.

Take some liquid out of the reservoir and leave the top off. Tilt the radiator forwards such that the in/out ports are at the highest point. This should dislodge any air trapped inside.

What rpm are you running the fans at? If the radiator is getting very hot (all over, evenly) this suggests you're at the maximum heat capacity for your radiator space. You should either increase fan speed or increase rad space.

Fans are run at full speed whilst under load if the gpu is idling i turn them down. Just ordered 2x vardars . Ill take the rad out as well before work and try disloge suspected air bubble as i say the fins do not get hot even if i leave the fans of so fingers crossed.

 

[fenchu]

well seems the radiator is either faulty or block with crap i just cleaned my new xspc 420 out with vinegar and water and i noticed the fins were warm as you would expect (with boiling water and vinegar) , cleaned the gt 240 and only a few fins warm up. Think the radiator has some kind of blockage in it. Gonna try few more clean outs with boiling water / vinegar before finishing of with distilled water.

I have the same problem that you already have, mines are 55 and 58 degrees, in a enthoo primo with a monster 4x120 and a 3x120 radiators, problem is that the air inside is insanely hot just because the vrms behind the titan x pcb goes to 90 degrees even 100 with thermal pads on.

the air in the room is over 34 degrees (summer is here and i'm in spain) so 20 degrees over ambient it's ok. I'm going to ek vardar f5's to solve the problem but i think it's not going to be more than 5 degrees below my actual temperature.

i'm asking ek if there's any water solution to watercool rear vrms but still nothing answered.


(Sorry for my english, i know that is not the best, i'm just trying to improve it but it wil take some time).

Your english is very well , i also noticed how hot the vrms get on back its crazy temps does nothing for the air inside of case. I just bought some grizzley heat pads to redo titan x in the hope of reducing temps a few degrees.

well after draining system and cleaning rads for hours just powered up pc and my temps already are looking better gpu at idle is now down to 22c / 24c prevously it was hovering around 31 32 @ idle. Just about to do some heaven runs will report back once done

Spoiler

last time i ran heaven i only needed 10 mins and the temp on gpu would rise to 65. Now im happy to report after 10 mins gpu under load is 36c , im sure that will rasie some under a few hours gaming but looking good so far


current setup :-

res > pump > 240 rad > gpu > 420 rad > res

Would just like to thank everyone who contributed to helping me , i have to say its greatly appreciated

 

[fenchu]

Did you put the EK vans in pull ? i would thought be a lot better at push ?
what are the fans in push atm ?

Glad temps came down !

Aerocool DS

Glad it worked out CPU next?

Yep give it a few weeks and will add cpu block in

 

[fenchu]

You could (in theory) add the CPU block without too much hassle, if you can get the positioning right, you might not even need to completely drain the loop.

If you run the tubes out of top the GPU block and run the CPU / GPU in parallel rather than in series.

Interesting ill have to have a look into this idea , how does it compare to series ? noob question but i am new to this if i take the plugs out of the top of gpu arent i going to have cooling fluid shoot out or ?

 

[fenchu]

Yes you would , just drain down to the level below the gpu.

thanks for advice , going to do some reading on parallel weekend and look at getting a block for cpu.
